Southern Ring Nebula | James Webb Space Telescope

Southern Ring Nebula | James Webb Space Telescope

The bright star at the center of NGC 3132, while prominent when viewed by the NASA/ESA/CSA James Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source. It has ejected at least eight layers of gas and dust over thousands of years.

But the bright central star visible here has helped ‘stir the pot’, changing the shape of this planetary nebula’s highly intricate rings by creating turbulence. The pair of stars are locked in a tight orbit, which leads the dimmer star to spray ejected material in a range of directions as they orbit one another, resulting in these jagged rings.

Hundreds of straight, brightly-lit lines pierce through the rings of gas and dust. These ‘spotlights’ emanate from the bright star and stream through holes in the nebula like sunlight through gaps in a cloud.

But not all of the starlight can escape. The density of the central region, set off in teal, is reflected by how transparent or opaque it is. Areas that are a deeper teal indicate that the gas and dust are denser – and light is unable to break free.

Data from Webb’s Near-Infrared Camera (NIRCam) were used to make this extremely detailed image. It is teeming with scientific information – and research will begin following its release.

This is not only a crisp image of a planetary nebula – it also shows us objects in the vast expanse of space behind it. The transparent red sections of the planetary nebula – and all the areas outside it – are filled with distant galaxies.

Look for the bright angled line at the upper left. It is not starlight – it is a faraway galaxy seen edge-on. Distant spirals, of many shapes and colours, also dot the scene. Those that are farthest away – or are very dusty – are small and red.

The Bigelow Expandable Activity Module (BEAM) is an expandable habitat technology demonstration for the International Space Station. Expandable habitats greatly decrease the amount of transport volume for future space missions. These “expandables” require minimal payload volume on a rocket, but expand after being deployed in space to potentially provide a comfortable area for astronauts to live and work. They also provide a varying degree of protection from solar and cosmic radiation, space debris, atomic oxygen, ultraviolet radiation and other elements of the space environment.

NASA’s Perseverance Scouts Mars Sample Return Campaign Landing Sites | JPL

NASA’s Perseverance Scouts Mars Sample Return Campaign Landing Sites | JPL



NASA’s Perseverance Mars rover used one of its navigation cameras to take these panoramas of a proposed landing site for the Mars Sample Return lander that would serve as part of the campaign to bring samples of Mars rock and sediment to Earth for intensive study.

NASA’s Perseverance Mars rover is conducting its science campaign, taking samples at Jezero Crater’s ancient river delta, but it is also been busy scouting. The six-wheeled rover is looking for locations where the planned Mars Sample Return (MSR) Campaign can land spacecraft and collect sample tubes Perseverance has filled with rock and sediment. The sites being scouted are under consideration because of their proximity to the delta and to one another, as well as for their relatively flat, lander-friendly terrain.

Mars Sample Return is a historic endeavor that would retrieve and deliver samples of that faraway terrain for intensive study in laboratories on Earth to look for signs of past microscopic life on the Red Planet. The strategic partnership between NASA and ESA (European Space Agency) would involve multiple spacecraft, including a rocket that would launch from the surface of Mars.

Engineers planning a Mars landing prefer to work with flatter ground because rocks and an undulating surface are harder to land on. With that in mind, the MSR Entry, Descent, and Landing team is looking for a pancake-flat landing zone with a 200-foot (60-meter) radius.

“The Perseverance team pulled out all the stops for us, because Mars Sample Return has unique needs when it comes to where we operate,” said MSR Program Manager Richard Cook of NASA’s Jet Propulsion Laboratory in Southern California. “Essentially, a dull landing place is good. The flatter and more uninspiring the vista, the better we like it, because while there are a lot of things that need to be done when we arrive to pick up the samples, sightseeing is not one of them.”

Flat-Out Inspirational

The first stage of MSR is already in progress: Perseverance has cored, collected, and sealed nine samples of Mars rock to date. The ninth, collected on July 6, is the first from Jezero Crater’s ancient river delta. The plan is for Perseverance to drop, or cache, sample tubes on the surface to await later retrieval during MSR surface operations.

Choosing an area that lacks large rocks (especially those over 7 1/2 inches, or 19 centimeters, in diameter), sand dunes, and steeply angled terrain would go a long way toward easing the path for an MSR recovery vehicle to efficiently grab tubes before heading to the MSR Sample Retrieval Lander and its Mars Ascent Vehicle.

Landing Strip

The MSR team calls the area they’ve been looking at the “landing strip” because – at least from images taken from spacecraft in orbit – it appears to be as flat and long as a runway. But they needed a rover’s-eye-view for a closer look.

“We had been eyeing these locations since before Perseverance’s landing, but imagery from orbit can only tell you so much,” said Al Chen, Mars Sample Return Systems Engineering & Integration manager at JPL. “Now we have some up-close-and-personal shots of the landing strip that indicate we were right on the money. The landing strip will more than likely make our shortlist of potential landing and caching sites for MSR.”

NASA’s Mars Sample Return Campaign promises to revolutionize humanity’s understanding of Mars by bringing scientifically selected samples to Earth for study using the most sophisticated instruments around the world. The campaign would fulfill a solar system exploration goal, a high priority since the 1970s and in the last three National Academy of Sciences Planetary Decadal Surveys.

This strategic NASA and ESA partnership would be the first mission to return samples from another planet and the first launch from the surface of another planet. The samples collected by NASA’s Perseverance Mars rover during its exploration of an ancient lakebed are thought to present the best opportunity to reveal clues about the early evolution of Mars, including the potential for past life. By better understanding the history of Mars, we would improve our understanding of all rocky planets in the solar system, including Earth.

Galaxy Cluster SMACS 0723: First Deep Field Image | James Webb Space Telescope

Galaxy Cluster SMACS 0723: First Deep Field Image | James Webb Space Telescope

This image shows thousands of distant galaxies of different shapes, sizes, colors, and brightness, with a scattering of bright foreground stars.

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. 

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

This image is among the telescope’s first-full color images.

Image of galaxy cluster SMACS 0723, affectionately known as Webb’s First Deep Field, captured by Webb’s Near-Infrared Camera (NIRCam), with compass arrows and color key for reference. 

The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

This image shows invisible near-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter. 

Because this is a deep field that shows objects at various distances and magnifications, there is no scale bar.

A Confetti-Like Collection of Stars | NASA's Spitzer Space Telescope (Infrared)

A Confetti-Like Collection of Stars | NASA's Spitzer Space Telescope (Infrared)

Before the James Webb Space Telescope, NASA's Spitzer Space Telescope was the largest infrared telescope. New Chandra x-ray observations have been used to make the first detection of x-ray emissions from young stars with masses similar to our Sun outside our Milky Way galaxy. The Chandra observations of these low-mass stars were made of the region known as the "Wing" of the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors. In this composite image of the Wing the Chandra data is shown in purple, optical data from the Hubble Space Telescope is shown in red, green and blue and infrared data from the Spitzer Space Telescope is shown in red. Astronomers call all elements heavier than hydrogen and helium - that is, with more than two protons in the atom's nucleus—"metals". The Wing is a region known to have fewer metals compared to most areas within the Milky Way. The Chandra results imply that the young, metal-poor stars in NGC 602a produce x-rays in a manner similar to stars with much higher metal content found in the Orion cluster in our galaxy.

Spiral Galaxy M106 | NASA's Spitzer Space Telescope (Infrared)

Spiral Galaxy M106 | NASA's Spitzer Space Telescope (Infrared)


A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas.

This galactic fireworks display is taking place in NGC 4258, also known as M106, a spiral galaxy like our own Milky Way. This galaxy is famous, however, for something that our galaxy does not have—two extra spiral arms that glow in X-ray, optical and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.

The anomalous arms are seen in this new composite image, where X-rays from NASA’s Chandra X-ray Observatory are blue, radio data from the NSF’s Karl Jansky Very Large Array are purple, optical data from NASA’s Hubble Space Telescope are yellow and infrared data from NASA’s Spitzer Space Telescope are red.

A new study made with Spitzer shows that shock waves, similar to the sonic booms from supersonic planes, are heating large amounts of gas—equivalent to about 10 million suns. What is generating these shock waves? Researchers think that the supermassive black hole at the center of NGC 4258 is producing powerful jets of high-energy particles. These jets strike the disk of the galaxy and generate shock waves. These shock waves, in turn, heat the gas—composed mainly of hydrogen molecules—to thousands of degrees.

The Chandra X-ray image reveals huge bubbles of hot gas above and below the plane of the galaxy. These bubbles indicate that much of the gas that was originally in the disk of the galaxy has been heated and ejected into the outer regions by the jets from the black hole.

The ejection of gas from the disk by the jets has important implications for the fate of this galaxy. Researchers estimate that all of the remaining gas will be ejected within the next 300 million years—very soon on cosmic time scales—unless it is somehow replenished. Because most of the gas in the disk has already been ejected, less gas is available for new stars to form. Indeed, the researchers used Spitzer data to estimate that stars are forming in the central regions of NGC 4258, at a rate which is about ten times less than in the Milky Way galaxy.

The European Space Agency’s Herschel Space Observatory was used to confirm the estimate from Spitzer data of the low star formation rate in the central regions of NGC 4258. Herschel was also used to make an independent estimate of how much gas remains in the center of the galaxy. After allowing for the large boost in infrared emission caused by the shocks, the researchers found that the gas mass is ten times smaller than had been previously estimated.

Because NGC 4258 is relatively close to Earth, astronomers can study how this black hole is affecting its galaxy in great detail.

The Tarantula Nebula | NASA's Spitzer Space Telescope (Infrared)

The Tarantula Nebula | NASA's Spitzer Space Telescope (Infrared)

Before the James Webb Space Telescope, NASA's Spitzer Space Telescope was the largest infrared telescope. This composite of 30 Doradus, aka the Tarantula Nebula, contains data from Chandra (blue), Hubble (green), and Spitzer (red). Located in the Large Magellanic Cloud, the Tarantula Nebula is one of the largest star-forming regions close to the Milky Way. Chandra's X-rays detect gas that has been heated to millions of degrees by stellar winds and supernovas. This high-energy stellar activity creates shock fronts, which are similar to sonic booms. Hubble reveals the light from massive stars at various stages of star birth, while Spitzer shows where the relatively cooler gas and dust lie.

The Spitzer Space Telescope (formerly SIRTF, the Space Infrared Telescope Facility) was launched by a Delta rocket from Cape Canaveral, Florida on August 25, 2003. Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer was the largest infrared space telescope before the James Webb Space Telescope (JWST) was launched in December 2021. The telescope was named in honor of American astronomer, Lyman Spitzer, who had promoted the concept of space telescopes in the 1940s. The retired Spitzer was the first observatory to provide high-resolution images of the near- and mid-infrared Universe. Webb, by virtue of its significantly larger primary mirror and improved detectors, will allow us to see the infrared sky with improved clarity (better spatial resolution), enabling even more discoveries.

NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, managed the Spitzer Space Telescope mission for NASA's Science Mission Directorate (SMD). Science operations were conducted at the Spitzer Science Center, at Caltech, in Pasadena, California. Spacecraft operations were based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.

Perseverance Rover July 7, 2022 Update: Searching for Sand Transport

"Perseverance is currently stopped for sampling at Skinner Ridge rock. Sampling activities constitute an important aspect of Perseverance’s mission, and the rover’s strategic path is developed around sampling stops. During these stops, the rover must remain stationary for at least twelve sols in order to conduct proximity science and activities related to abrasion and coring. But being parked in one location for this extended period of time is also useful for something else. "

"Sampling stops provide rare opportunities to conduct “change detection” experiments, which are used to monitor wind-driven—or aeolian—transport of sand. The basic concept behind change detection is simple: compare identical images of the surface acquired at different times to search for wind-induced movement of sand. These observations can be used to deduce information about the relative strength and direction of winds blowing in the time between the two images. Sand deposits and aeolian bedforms (such as the sand ripples seen in the accompanying Mastcam-Z image) are ideal targets for change detection."

Portrait of Globular Cluster Terzan 2 | Hubble

Portrait of Globular Cluster Terzan 2 | Hubble

The globular cluster Terzan 2 in the constellation Scorpio features in this observation from the NASA/European Space Agency (ESA) Hubble Space Telescope. Globular clusters are stable, tightly gravitationally bound clusters of tens of thousands to millions of stars found in a wide variety of galaxies. The intense gravitational attraction between the closely packed stars gives globular clusters a regular, spherical shape. As a result, images of the hearts of globular clusters, such as this observation of Terzan 2, are crowded with a multitude of glittering stars.  

Hubble used both its Advanced Camera for Surveys and its Wide Field Camera 3 in this observation, taking advantage of the complementary capabilities of these instruments. Despite having only one primary mirror, Hubble’s design allows multiple instruments to be used to inspect astronomical objects. Light from distant astronomical objects enters Hubble and is collected by the telescope's 2.4-meter primary mirror; it is then reflected off the secondary mirror into the depths of the telescope, where smaller mirrors can direct light into individual instruments. 

Each of the four operational instruments on Hubble is a masterpiece of astronomical engineering in its own right, and contains an intricate array of mirrors and other optical elements to remove any aberrations or optical imperfections from observations, as well as filters which allow astronomers to observe specific wavelength ranges. The mirrors inside each instrument also correct for the slight imperfection of Hubble's primary mirror. The end result is a crystal-clear observation, such as this glittering portrait of Terzan 2.

Spitzer Space Telescope Mission Poster | NASA/JPL

Before Webb, Spitzer Revealed An Infrared Universe


This is an illustrated poster of the Spitzer Space Telescope along with the exoplanets of the TRAPPIST-1 system.

The Spitzer Space Telescope, launched in 2003, on a mission to become NASA’s premier infrared light observatory. It offered astronomers an unprecedented infrared view of the universe, allowing us to peer into regions of space that are hidden from optical telescopes with unprecedented clarity and sensitivity. One of NASA’s Great Observatories, Spitzer discovered a ring of Saturn, studied some of the farthest galaxies, and identified two of the most distant supermassive black holes ever discovered, among other accomplishments in its 16 years of operation.

The study of exoplanets—planets outside our solar system—was not one of Spitzer’s original goals. But innovations during its mission improved Spitzer's precision and enabled it to become a critical tool for exoplanet work. Spitzer marked a new age in planetary science by being the first telescope to directly detect light from exoplanets. It has played a key scientific role in everything from planets larger than Jupiter to small, rocky worlds that may be similar to Earth.

In 2017, Spitzer helped reveal TRAPPIST-1, the first known system of seven Earth-sized planets. The discovery set a new record for the greatest number of habitable-zone planets found around a single star outside our solar system. Data from Spitzer also showed that all of these planets are likely to be rocky. Studying TRAPPIST-1 leads scientists a step closer to answering the question "Are we alone?"

This poster depicts the TRAPPIST-1 planets, some of which were discovered by Spitzer. The physical characteristics of the planets are not currently known, beyond their mass and distance from the TRAPPIST-1 star, which is visualized in the background. The James Webb Space Telescope is expected to teach us more about this fascinating system.

Before Webb, NASA's Spitzer Space Telescope Revealed An Infrared Universe

Before Webb, NASA's Spitzer Space Telescope Revealed An Infrared Universe

Mission Overview: After 16 years of unveiling the infrared universe, NASA's Spitzer Space Telescope left a singular legacy. As one of NASA’s four Great Observatories—a series of powerful telescopes including Hubble, Chandra and Compton that can observe the cosmos in different parts of the electromagnetic spectrum—Spitzer quickly became a pioneer in the exploration of worlds beyond our human vision. From stars being born to planets beyond our solar system (like the seven Earth-size planets around the star TRAPPIST-1), Spitzer's science discoveries continue to inspire.  

Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer was the largest infrared space telescope before the James Webb Space Telescope (JWST) was launched in December 2021. The telescope was named in honor of American astronomer, Lyman Spitzer, who had promoted the concept of space telescopes in the 1940s.

Stellar Snowflake Cluster | NASA's Spitzer Space Telescope (Infrared)

Stellar Snowflake Cluster | NASA's Spitzer Space Telescope (Infrared)

Before the James Webb Space Telescope, NASA's Spitzer Space Telescope was the largest infrared telescope. Newborn stars, hidden behind thick dust, are revealed in this image of a section of the Christmas Tree cluster from NASA's Spitzer Space Telescope, created in a joint effort between the Spitzer infrared array camera and multiband imaging photometer instruments.

The Snowflake Cluster was granted its name due to its unmistakable pinwheel-like shape and its assortment of bright colors. The Christmas Tree star formation consists of young stars obscured by heavy layers of dust clouds. These dust clouds, along with hydrogen and helium are producing luminous new stars. The combination of dense clouds and an array of colors creates a color map filled with varying wavelengths. As seen in this image taken by the Spitzer Space Telescope, we are able to differentiate between young red stars and older blue stars.

The Spitzer Space Telescope (formerly SIRTF, the Space Infrared Telescope Facility) was launched by a Delta rocket from Cape Canaveral, Florida on August 25, 2003. Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer was the largest infrared space telescope before the James Webb Space Telescope (JWST) was launched in December 2021. The telescope was named in honor of American astronomer, Lyman Spitzer, who had promoted the concept of space telescopes in the 1940s. The retired Spitzer was the first observatory to provide high-resolution images of the near- and mid-infrared Universe. Webb, by virtue of its significantly larger primary mirror and improved detectors, will allow us to see the infrared sky with improved clarity (better spatial resolution), enabling even more discoveries.

NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, managed the Spitzer Space Telescope mission for NASA's Science Mission Directorate (SMD). Science operations were conducted at the Spitzer Science Center, at Caltech, in Pasadena, California. Spacecraft operations were based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.
